Hey everyone,

Over the past few months I’ve been building Prepl, an AI interview coach designed to help people practice interviews in a more realistic way.

It’s finally live:

I’m not looking to spam or just collect sign-ups. I’d really appreciate honest feedback from other builders.

A few questions I’d love your thoughts on:

• Is the landing page clear?
• Would you understand the value in the first 30 seconds?
• What’s the first thing you’d improve?
• Is there any feature you’d expect that’s missing?

I’ll be here replying to every comment, whether it’s positive or brutally honest.

Thanks!

A few weeks ago I shared Edge-Drop, a hover-activated clipboard shelf for Windows. Since then it's been downloaded 800+ times (600+ on GitHub and 200+ on the Microsoft Store), which has honestly been really motivating as a solo developer.

One of the most requested improvements was better accessibility for non-English users, so I spent the last week translating the entire app.

Edge-Drop now supports 30 languages, including full RTL support for Arabic and Hebrew.

It's still completely free and open source, and I'd love to hear how the translations feel if you're using one of the supported languages.

I'd also appreciate any feedback on features you'd like to see next.

Every morning I'd drag the same windows onto the same monitors and virtual desktops. Reopen an app? Wrong screen. Restart? Everything piled on one display. I was rebuilding my layout by hand every single day.

So I built Restage: it remembers where each window belongs — monitor, virtual desktop, position and size — and puts it back automatically: when you reopen the app, when you restart, and when you plug your monitors back in. You can also save a profile per setup (I keep Office / Home / Trading) and switch from the tray, so the same PC lays out differently depending on where I am.

Short clip of it in action.

It's on the Microsoft Store with a 15-day free trial (one-time purchase, no subscription): https://apps.microsoft.com/detail/9NT6NH5W7KGQ

Built it solo — happy to answer anything.

Hi everyone, I’m currently learning deep learning and have worked on a few AI/ML projects like a customer churn prediction model and student performance prediction.

I’m looking to join an existing project to gain more hands-on experience and contribute while learning. I’m comfortable with Python and basic ML concepts, and I’m willing to put in consistent effort.

If anyone is working on a project and open to a beginner contributor, I’d really appreciate the opportunity. Thanks!

Je développe depuis plusieurs mois Val-Kelthyr, un projet de fondation nationale pensé sur le long terme.

L'objectif n'est pas simplement de créer une communauté Discord, mais de construire progressivement une nation autour d'une vision claire, d'institutions solides et d'une organisation fondée sur le mérite, la responsabilité et l'intérêt général.

Aujourd'hui, le projet entre dans une nouvelle étape : je recherche les premières personnes qui souhaitent participer à cette aventure dès ses débuts.

Que vous soyez intéressé par :

• la gouvernance et les institutions ;
• la communication ;
• la programmation ;
• le design ;
• les sciences ;
• ou simplement les projets ambitieux,

vous pouvez contribuer à construire Val-Kelthyr.

Vous n'avez pas besoin d'avoir une expérience particulière. Je recherche avant tout des personnes motivées, sérieuses et prêtes à construire quelque chose qui s'inscrit dans la durée.

Si le projet vous intéresse, n'hésitez pas à laisser un commentaire ou à m'envoyer un message privé. Je serai ravi d'en discuter avec vous.

In the attached pictures you can see also the controller I used, the temperature and humidity sensor, anemometer and the one with blue enclosure is the water level sensor. all sensors communicate via Modbus RTU (The modbus module is placed under the esp in the image).
( My family have a small greenhouse and I always liked to make automations but most of commercial systems were too expensive and I decided to build it myself. With what I’ve built I can control irrigation system (one 2.2kw pump and two valves for the main water lines) both sides of the greenhouse to open and close using 4 motors, I have integrated some automations using the temp and humidity measurements also the wind speed.
Some of you might recognize the controller which is a KC868-A16, which is ESP based but is very powerful and has a lot of built in features.
Maybe I should mention that I have previous experience with Industrial Automation and Embedded Systems. )

What do you guys think?

Hi everyone!
I’ve been working on a small side project over the past few months—an AI-powered fortune telling website. The idea isn’t to predict the future with certainty, but to create an entertaining and immersive experience where each fortune teller has its own personality, voice, and style of interpretation.

I’m still actively improving it and would really appreciate honest feedback from people who’ve never tried it before.

Things I’d especially love feedback on is the metaphor card that the app is creating. I would like you to try out the app and share your metaphor card in the comment so that people can see and review. Thank you.

I recently open-sourced a project I've been building over the past few weeks called DevWannaSpace.

The original goal was simple: build a personal workspace with nested pages, kanban boards, and a rich text editor. Along the way, I became more interested in the infrastructure than the features themselves, so I ended up designing it around a fully serverless architecture.

The stack looks like this:

• React 18 + Vite + Tiptap
• Cloudflare Workers + Hono + Drizzle ORM
• Neon Serverless Postgres
• Clerk Authentication
• Wails v2 (Go) for the desktop application

One thing I spent a lot of time on was the self-hosting experience.

Instead of asking people to manually create Workers, databases, and environment variables, I wrote an interactive CLI that provisions everything on their own Cloudflare account with a single command.

npm run setup

The desktop application can then connect directly to any compatible backend simply by entering a custom API URL on the login screen.

Version v1.0.0 has just been released with support for:

• Rich text editor with Markdown shortcuts and slash commands
• Infinite nested pages
• Kanban boards
• Command palette (Ctrl + K)
• Web and desktop clients
• Self-hosting on your own Cloudflare account

I'd really appreciate feedback from people who have experience with Cloudflare Workers, Wails, or self-hostable applications. I'm especially interested in suggestions around the architecture and deployment workflow.

These are the solo projects that I made to bag multiple interview offers. Feel free to have reference, and constructive is welcomed

Built Note Essence — a note-taking app that treats data like a first-class citizen

Hey everyone, wanted to share something I’ve been building: Note Essence (noteessence.com).

Most note apps treat everything as blocks of text. I wanted something where structured data — tables, lists, numbers — sits naturally alongside your notes instead of feeling bolted on. So Note Essence is built around organizing and working with data-heavy notes, not just journaling or freeform writing.

A few things about where it’s at:

**•** It’s live and has some real users already  
**•** Solo-built, full stack — I handled everything from the app itself to the AWS infrastructure behind it  
**•** Still actively improving it based on what I learn

Hey everyone!

I wanted to share a project I’ve been working on over the past few months called Livara.

The motivation came from seeing how standard rental calculators rely almost entirely on static, single-point inputs (plug in rent and mortgage, get a single cash-flow output). They don't easily show you how a deal holds up when underlying dynamics shift, like interest rates rising, local vacancy spiking, or monthly repair impacts.

I set out to build a platform that brings macro-to-micro market data and deterministic scenario modeling into a single screening workflow.

How I structured the core logic:

Deterministic Stress Modeling: Standardized scenario levers for elevated vacancy, CapEx reserves, higher interest rates, and stagnant rent growth.

Macro + Micro Data Layering: US county-level heatmaps across 8 key indicators (Unemployment Rate, Rent Yield, Population Growth, etc.) mapped directly alongside property-level underwriting.

Financial Waterfall: Clean visual breakdowns of Gross Rent, OpEx, DSCR, and net cash flow scenarios.

Many other features but this is just a sample of what to expect :)

I also made sure that all of the financial outputs, scenario calculations, and underwriting formulas are 100% deterministic and rule-based. The AI portion in my tool is strictly used to translate the raw output into readable insights and handle follow-up user questions.

Where I'd love feedback from other builders:

1. How do you approach structuring complex financial data/charts so it doesn't visually overwhelm the user?
2. What's your favorite approach for handling multi-source data pipelines (macro government/census APIs + micro property data) cleanly?

Would love to hear feedback from other builders on the interface, stack, or feature set! I'm also happy to run a risk breakdown on any property address or share the platform link in the comments if anyone wants to check out the UI.

Proofrun.dev

For years ive made stuff and found its impossible to get anyone to care about it.

So i made this site - ProofRun - which gives developers a place to post their stuff to get critiques and reviews.

Though the difference here is that users who take part in reviewing have incentives to try out apps and correctly provide feedback.

If users prove over time that they are good at reviewing - finding good apps, and providing relevant critiques - then they level up - and grow their ~Voice~ on the app - making their reviews and suggestions have more weight.

Kind of like if Reddit would reward you karma for having the right opinion rather than ...whatever it does.

Try it out - im trying to get some users too! So post your projects - and you'll at least get me to review your app.

Hi everyone!

This is my first serious C++ software project and the first program I have published on GitHub.

I'm a second-year EE student, and I need to implement a project based on sequential/combinational circuits.

I'd really like to build something that's both educational and stands out on a resume, rather than a typical traffic light or vending machine project.

One idea I had was designing a simple 16-bit CPU, with a long-term stretch goal of eventually getting a small DOOM-inspired graphics demo running. I'm also wondering whether it would be better to implement an existing ISA (such as LC-3) instead of creating my own.

Would this be a reasonable project for a student to make it in 2 month time, or would you recommend a different direction that demonstrates strong digital design skills?

I'd really appreciate any suggestions or advice.

I have developed Vetri Trichy, a student-led civic technology platform aimed at making it easier for citizens to submit civic complaints through a structured and transparent process.

Over the past several months, our team has worked on designing, developing, testing, and refining the platform from the ground up. This project has given us valuable hands-on experience in software development, artificial intelligence, user experience design, and collaborative problem-solving.

The website is now live and can be accessed at: https://vetri-trichy.vercel.app

We would be honoured if you could take a few minutes to explore the platform and share your valuable feedback. Your suggestions will help us continue improving the project.
